Definitions

  • the invention is directed to an improved press for rendering fatty bones in order to obtain rendered bones of low fat content suitable for the production therefrom of gelatin and also glue or animal meal.
  • Fatty bones are, for example, slaughter house or butcher's shop offal containing meat and fats besides bones. Loads of fatty bones supplied vary greatly and their content in soft substances (meat, fats, skins . . . ) can range between 0 and 40-50% according to their source, the mean content being about 15%. Due to their nature fatty bones supplied cannot be homogenized beforehand. They must be used as such. Fatty bones are usually treated in order to take off the major part of fats and non-collagenous proteinacious material and obtain the desired particle size range. Most often the bones are first sorted out for eliminating foreign substances such as pieces of iron or plastic material and are afterwards sent to a prebreaker and a breaker.
  • the broken bones are heated by steam to a temperature of about 90° to 95° C. and charged in a press in order to recover a solid cake constituted in major part by bones and a liquid constituted by molten fats, water-soluble substances and in some cases, bone powder.
  • the separated liquid is treated in order to recover fats and proteinous substances.
  • the bones are dried and optionally treated for the production of gelatin.
  • the driving tube also supports a threadless zone provided by a single cylindrical sleeve portion located at the outlet of the last stage of the press.
  • the press may include two to six stages, but more often four. Such presses are described for example in U.S. Pat. Nos. 3,398,677 and 3,398,678.
  • presses are currently used for rendering fish wastes, separating fat from cracklings in crude fats, extracting oil from oleaginous seeds such as soja, peanuts, etc. They can also be used for rendering slaughter house or butcher's offal containing a high proportion of soft substances (meat, fats, skins, etc.). But when treating fatty bones containing less than 20% of soft substances, the bones do not move forward regularly in the press, thus causing clogging with resultant jamming or breaking of the press.
  • the present invention relates to an improved multistage continuous screw press usable for rendering bones containing less than 20% of soft substances without jamming or breaking of the press.
  • the improved press is obviously also usable for rendering fat containing higher percentages of soft substances.
  • the present invention relates to a multistage continuous screw press constituted by a cylindrical cage or casing in which is located a drive arbor or tube on which, in each stage, is secured a continuous screw collar, the inside diameter of which increases in the direction of feeding circulation of the treated product and the outer diameter of which is slightly less than the inside diameter of the cage and on which, between two successive stages, is located a threadless transition zone formed by two cylindrical surface portions or sleeves integral with one another.
  • One of the sleeves is fixed to the continuous screw collar of the preceding stage and has an outer diameter equal to the greatest inner diameter of the screw collar of the preceding stage.
  • the other sleeve is fixed to the continuous screw collar of the next stage and has an outer diameter equal to the smallest inner diameter of the continuous screw collar of the next stage.
  • An important feature of the present invention is in connection with the area of the threadless zones where there are provided impingement elements in the form of at least two L-shaped knives arranged in such a manner that the branch of the L-shaped portion fixed to the cage is at the level of the sleeve portion having the greatest outer diameter and that the perpendicular branch portion is at the level of the sleeve portion having the smallest diameter.
  • Knits in each transition zone can be used but it was found that two knives are sufficient in most cases. They are generally regularly spaced in a cross-section of the cage. When there are two knives they are preferably on the same diameter, preferably along a horizontal diameter portion. When there are three knives they are disposed at an angle of 120°.
  • the two branches of the knife are often of different length, with the longest branch preferably fixed to the cage. The best results are obtained when the gap between the knife and the outer part of the threadless zone is equal to about 5 mm.
  • the end of the branch fixed to the cage and the edge of the perpendicular branch facing the feeding or upstream end of the press are preferably bevelled.
  • the knives are preferably fastened in slots cut out in the cylindrical cage. They can be welded or riveted but they are preferably held by screws in order to be easily replaced.
  • FIG. 1 is a longitudinal view with half the casing removed to illustrate the multistage screw and knife arrangement therein;
  • FIG. 2 is an enlarged side elevation of one of the knives
  • FIG. 3 is a further enlarged plan view of one of the knives.
  • FIG. 4 is a fragmentary detail in section on line 4--4 of FIG. 1 to show the slat construction of the casing.
  • the press assembly includes a cage or casing 10 formed of longitudinal slats l0a suitably assembled and mounted and in which is located a drive arbor or tube 12 which is suitably mounted and coupled to a motor (not shown).
  • the press assembly includes an inlet compartment 14 and four screw stages 16, 18, 20 and 22. The length of the stages decreases in the direction of feed circulation of the product, with stage 16 being the longest stage and stage 22 being the shortest.
  • drive tube 12 supports a continuous screw collar 24 having a constant inside diameter in complement to the diameter of arbor portion 12a.
  • the drive tube 12 supports continuous screw collars 26, 28, 30 and 32, respectively, the inside diameter of which increases in the direction of circulation of the product in complement, respectively, to the inclined arbor portions 12b, 12c, 12d, 12e.
  • the outer diameter of the continuous screw collars 24, 26, 28, 30 and 32 is constant and slightly smaller than the inside diameter of the cage 10 in order that the continuous screw collars can freely rotate in the cage.
  • transition zones 34, 36 and 38 that is, zones without screw collars therein.
  • Each zone is constituted by two cylindrical surface or sleeve portions: 40 and 42 for zone 34, 44 and 46 for zone 36, 48 and 50 for zone 38.
  • sleeve 40 has a diameter equal to the largest internal diameter of continuous screw collar 26 and sleeve 42 has a diameter equal to the smallest internal diameter of continuous screw collar 28.
  • the knives 52, 52a, 54, 54a, 56, 56a are fixed to the wall of cage 10 within the longitudinal extent of the threadless zones 34, 36 and 38, respectively. According to the embodiment of the invention shown, two knives are disposed on a horizontal diametral portion in each zone.
  • a sleeve or surface portion 58 is located at the outlet end of the last stage 22 with a diameter equal to the largest internal diameter of the screw collar 32.
  • Four breaker clips 60 are equidistantly fixed to the casing 10 around the sleeve portion 58 at angles of 90° relative to one another and at angles of 45° relative to a horizontal line for the purpose of breaking the issuing cake and facilitating its forward movement.
  • the knives are usually formed of steel and are L-shaped as shown and with reference to FIG. 2, the relative dimensions of the branches may vary from one stage to another.
  • the knives in a press assembly of 350 to 450 cm in length and a casing of 65 to 55 cm in diameter may have the following range of dimensions, and the axial extent of the transition zones as well as relative radial extents of the cylindrical surface or sleeve portions will be dimensioned accordingly to accommodate the knives in each zone with proper clearance:
  • the thickness of the knives is variable and may, for example, be of the order of 10 mm.
  • each of the knives is mounted in its respective zone in similar manner and reference will be made in FIG. 2 for a description of the mounting of knife 54.
  • the elongate edge 62 is apertured for mounting in a slat or runs in one of the slats 10a by means of screws or like fastening means. This will locate the inner edge 62 in overlapping position relative to the large diameter cylindrical surface portion 44 with suitable clearance and with the bevelled edge 62a facing the material issuing from stage 16.
  • the lower edge 66 of the perpendicular branch of the knife will be in overlapping relation to the smaller diameter surface 46 with suitable clearance and with the bevelled edge 66a alone facing the material issuing from stage 16.
  • the material is conveyed and introduced in conventional manner from a hopper 68 to the upstream chamber 14 of the screw press assembly and is progressed through the press to the collection and discharge assembly for delivery through opening 70 for ultimate conveyance and disposition as desired.
  • the fluid and fines expressed through the slat apertures will be collected in known manner.
  • the material is thus subjected to progressively higher pressure in each stage but with some reduction in pressure and reorientation as it passes through each transition zone between adjacent stages.
  • the clips Upon egress of the processed material, the clips so further divide the material prior to discharge through the end aperture 70.
